The dissertation examines how synchronous text-based computer-mediated communication (SCMC) tasks may affect English as a Second Language (ESL) learners' development of second language (L2) and academic literacy. The study is motivated by two issues concerning the use of SCMC tasks in L2 writing classes. First, although some of the alleged…

This study investigated how task complexity affected native and non-native speakers' speaking performance in terms of a measure of communicative success (functional adequacy), three types of fluency (breakdown fluency, speed fluency, and repair fluency), and lexical diversity. Participants (208 non-native and 59 native speakers of Dutch) carried…

This longitudinal study examines the acquisition of tense and agreement morphology by child L2 learners in an early stage of language acquisition. The objectives of this study are twofold. The first is to observe the development of verb inflections and syntactic competence over time from an early stage by Chinese child L2 learners of English. The…

This paper reports on the findings of a case study that set out to discover student behaviour in the computer room while the participants were engaged in a collaborative computer-assisted language learning (CALL) task in form of an electronic role-play which was designed for advanced learners of business German. The task mainly utilized…

Whereas second language (L2) education research has extensively examined how different types of interactional feedback can be facilitative of L2 development in meaning-oriented classrooms, most of these primary studies have focused on recasts (i.e., teachers' reformulations of students' errors). Some researchers have claimed that recasts serve an…

Integrated writing tasks that involve different language modalities such as reading and listening have increasingly been used as means to assess academic writing. Thus, there is a need for understanding how test-takers coordinate different skills to complete these tasks. This study explored second language writers' strategy use and its…

Purpose: Two new treatments, 1 based on sentence to picture matching (SPM) and the other on object manipulation (OM), that train participants on the thematic roles of sentences using pictures or by manipulating objects were piloted. Method: Using a single-subject multiple-baseline design, sentence comprehension was trained on the affected sentence…

This article presents a review of the Children's Organizational Skills Scales (COSS) which were designed to assess how children organize their time, materials, and actions to accomplish important tasks at home and school. The scale quantifies children's skills in organization, time management, and planning (OTMP). The COSS is a multi-informant…

Human factors (HF) is a discipline often drawn upon when there is a need to train people to perform complex, high-stakes tasks and effectively assess their performance. Complex tasks often present unique challenges for training and assessment. HF has developed specialized techniques that have been effective in overcoming several of these…

This study examined the effectiveness of explicit instruction on second language (L2) learners' implicit and explicit knowledge of English. Explicit instruction on the generic and non-generic use of English articles was delivered by CALL activities. Four tasks assessed acquisition: elicited imitation, oral production, grammaticality judgement, and…

Research indicates that oral narrative is the discourse form that functions as a bridge between conversational oral language and language skills that contribute to the acquisition of literacy in children (Westby, 1991). Learning to tell stories, therefore, is important to children's literacy development. Mastering extended discourse tasks such as…

The human capacity to synchronize body movements to an external acoustic beat enables uniquely human behaviors such as music making and dancing. By hypothesis, these first evolved in human cultures as fundamentally social activities. We therefore hypothesized that children would spontaneously synchronize their body movements to an external beat at…

Vision researchers have investigated the differences between global and local feature perception. No one has, however, examined the role of global and local feature discrimination in sustained attention tasks. In this experiment participants performed a sustained attention task requiring either global or local letter target discriminations or…

While autism is one of the most intensively researched psychiatric disorders, little is known about reasoning skills of people with autism. The focus of this study was on defeasible inferences, that is inferences that can be revised in the light of new information. We used a behavioral task to investigate (a) conditional reasoning and (b) the…

Neural resources subserving spatial processing in either egocentric or allocentric reference frames are, at least partly, dissociated. However, it is unclear whether these two types of representations are independent or whether they interact. We investigated this question using a learning transfer paradigm. The experiment and material were…
